Interesting, this sounds like a serious bug.
But I tried to reproduce this in latest master, but following test passed
for me (add to TestMetadataTables):
```
@Test
public void testFilesVersionAsOf() throws Exception {
// Create table and insert data
sql(
"CREATE TABLE %s (id bigint, data string) "
+ "USING iceberg "
+ "PARTITIONED BY (data) "
+ "TBLPROPERTIES"
+ "('format-version'='2', 'write.delete.mode'='merge-on-read')",
tableName);
List<SimpleRecord> recordsA =
Lists.newArrayList(new SimpleRecord(1, "a"), new SimpleRecord(2,
"a"));
spark
.createDataset(recordsA, Encoders.bean(SimpleRecord.class))
.coalesce(1)
.writeTo(tableName)
.append();
Table table = Spark3Util.loadIcebergTable(spark, tableName);
Long currentSnapshotId = table.currentSnapshot().snapshotId();
List<SimpleRecord> recordsB =
Lists.newArrayList(new SimpleRecord(1, "b"), new SimpleRecord(2,
"b"));
spark
.createDataset(recordsB, Encoders.bean(SimpleRecord.class))
.coalesce(1)
.writeTo(tableName)
.append();
List<Object[]> res1 = sql("SELECT * from %s.files VERSION AS OF %s",
tableName, currentSnapshotId);
Dataset<Row> iceberg =
spark.read().format("iceberg").option("snapshot-id",
currentSnapshotId).load(tableName + ".files");
List<Row> res2 = iceberg.collectAsList();
}
```
Not sure what I'm missing here
